Using Asus Eee PC (Linux) to acess OctoPi, log in issue


I have an Asus 701 running Ubuntu, machine is about 10 years old and was languishing in a goody box in the closet.

I set up a new Pi 3 B+ and have successfully connected to it. The rub is in trying to log in. When I click the Login button nothing happens. If I hover I see this:


I can change from tab to tab, but logging in ain't gonna happen at this point. I realize the PC is long in the tooth but it would make an excellent display/control panel out of something that I hate to throw away. The battery is even good, with a run time of a couple hours!

I know nada about both Java and Linux...
